To all whom it may concern. .Be it known that I, PETER Improvements in Brooms or Brushes, of which the followln'g 1s a'specificat on. p

The present invention relates to brooms or brushes, and, in fact, to any article of that nature which comprises tufts of brush mate rial and aholder forv such tufts. It is particularly suited for brooms of such stiff and coarse character. as are used for streetsweep-i ing, and of which the brush material consists of ratan orother reeds, either split or whole, and I have, for the purposeof illustration in the drawings furnished herewith, shown abroom of this specific character. It isto be understood,however, that the prlnciples 1n which the invention consists are applicable to brooms or brushes ofa great variety of sizes and contalningbrush materlals of various sorts, useful for different purposes.

One object which I havehad particularly in view has been to produce a construction of the sort indicated, which can be made by the blind, and one which also is strong .and rigid, and is adapted to secure the tufts of brush materialwith exceedingly great firmness. 7 i

The principles and means in whlch the 1nvention conslsts may be best explained 1n connection with the following description and appended drawings of one form of broom which I have made embodying these principles. V

' trated in Figs. 1 to 4: ma represent'the tufts of brush materiahwhich are here shown asv being composed of split ratan andqb repre-f sents the handle. 'The' form now being de-'v 60" scribed consists of seven '.tufts in line,'-of. which the middle tuft is composed of strips or reeds arranged so'as to surround the lower end of the handle.

These tufts are mounted and securedin two holders orbinders,'eaohconsisting of alike, and are shown in thedra'wings as being exactly. alike, as to, each of the two forms represented, wherefore a description in ,de-' tail of one is sufficientforboth, and both are designated by the samej'reference letters. I 75 length or in any selected'p'arts. The ends of the wires are provided with eyes e, f, and between the ends each wire is bent in a somewhat zigzag form tomakehalf-sockets 9 and relatively narrow loops or tongues h; The half-sockets are adapted to-receive the tufts" a, and the intermediate-loops to pass between the tufts. 7 s T In making up the broom, the tufts. are preferably first bunched in anysuitable way, including the modes of operation now practised, and, when thus assembled, are laid in"- the'socket bends of one of the holder menu'- bers; Then the coinplemental member ofjthe. 100 same holder is laidagainst the opposite sides of the tufts so placed, and" pressure is 1 exerted upon one of these members toward the other, enough to bring the eyes at their ends intoregistry. Conveniently, the menu 0 bers of both holders which form the socket halvesat the same side of the broom are laid in a properly formed bed, and the tufts are I placedin a hoiizontabposition at the same time in both, the opposite members of the 1 two members, one of which isarranged to; grip thetufts near theirupp'e'r. ends, theother to grip the tufts at a-lower point. The upper andlower holders are substantially i I ping narrow loops or tongues, and giving two holders then being preferably applied and pressed down upon the tufts at the same time. When the complemental eyes are so registered, they are secured together by lock- 1 ing pins j and is, as shown. in Fig. 1. Here the same pins are shown as passing through the eyes on the same end of the broom of both holders; but, of course, this detail may be modified, and separate pins or rivets of any suitable sort applied independently to each holder.

. I The operation thus far described results. in the halves of one or both holders being secured together at their ends but not else where, each of the holder members then having narrow loops passing between the tufts and overlying one another, but having no interlocking effect. Then the holders are locked between the adjacent tufts by passing a tool through each pair of overlap- ,"the two a' twist about a line which runs from one end to the other of the connected members. This twisting'movement carries thetongue which projects from the memberv c downward between two adjacent sockets g of the opposite member 0?, and at the same time bends the underlying loop or tongue of the member (Z upward between the'opposite tufts. By carrying forward the twisting ef-" fect more or less far, the socket halves may be drawn more or less tightly about the tufts. It becomes possible thus to apply such a firm grip as to makeit practically impossible for the tufts or any part of them to work loose and vfall out.

Of course, any means already known for binding the indivldual pieces in a broom tuft together, or for producing lncreased friction between their contacting surfaces,.

such asglue, cement, a coating of paint, a

filling of rosin or whatever,may be used.

in making brooms according to my inven t1on, to prevent interior reeds from slipplng endwise past the outer reeds gripped by the holders.

All of the tufts are thus lndivlduallyf gripped as tightly as may be needed, in two places. a a

The upper and lower holders need not be exactly alike insize and dimensions, and l.

contemplate making them different to this extent, that in the lower holder the loops orsockets may be widened or spaced farther apart than'those of the upper holder, while the sockets of the'latter may be narrower or spaced closer together than as shown in these drawings.

clined' toward one another, with the result that their upper or butt ends are placed Thereby the tufts are in compared with other is its simplicity, and

latter is even recessed at its lower end, as

indicated at Z) and b ato contain them, and no reeds are around the handle. The binders forthis form are in principle like those already described, but different in the respect that the middle socket or loop it is made of extra ,width, being, in fact, .sufiiciently wide toembrace the two middle tufts and the interposed'handle; There is substantially no greater distance between the two tufts which are thus placed against the handle than between any other two, because, as appears from Fig. 5, the handle may be recessed deeply enough, without objectionable loss'of strength, to make its thickness between the tufts nogreater than the space needed for the locking loops between other tufts. i

As have already intimated, the same invention may be applied to making brushes of various sorts, and inthis use of the term brush'I intend to include brooms as well, and indeed all articles of like nature which comprise a holder and tufts of any sort of brush material, whether such mate- I rial 1s bristles, broom-corn, reeds, or what not; and the term brush as used in the claims has like significance. Thus, for making brushes of larger or smaller size, wire of largeror smaller gage may be used in the holders, andbrush material of the more fragile sorts may be protectedfrom being cut or broken underthe pressure of these holder members-by a wrapping of compara,

tively stiff material;'or the holder members, where they pass around the tufts, may be so flattened as to distributethe'pressure which they apply. Again, the brush may be made of tufts and holders without the long handle I such is required for sweeping streets or floors, and a head'or back of "the proper sort may be applied I It is within my contemplation, and within the protection of the appended claims, to make the'intermediate loops or tongues h relatively shorter than as shown here, and

' to interlock the overlapping tongues of the f complemental members one with another by keys or rivets, in essentially the same manner that the eyes 6 and f are locked together, instead of by twisting said loops around one another. I

One great advantage of this invention, as

with the holders, and the latter made perfectly secure, by manipulation, for the pro duction of which only a sense of touch is necessary, wherefore the brush can be made entirely by blind workers. Particularly, there is no need fOr driving nails. Another advantage is that the tufts are more securely clamped and held than they are in What I claim and desire to secure by Letters Patent is:

1. A brush comprising tufts and a holder, said holder having opposite complemental members each with the complemental parts of sockets to receive the tufts and with in-' termediate pro ecting tongues, the tongues of said members being interlocked with one another and the said socket, parts belng forcibly held against the interposed compacted tufts and securing the latter against relative endwise movement.

2. A brush comprising tufts of brush material, and holders therefor consisting of complemental members formed with opposite bends each arranged and adapted to furnish the half of a tuft-receiving socket com-. plemental to the opposite bend of the other member, and said members having between said socket-forming bends, loops which are bent up out of the plane of said bends; the loops contiguous to one another of the complemental members extending in opposite directions and being overlapped and interlocked with one another.

3. A brush made of tufts, and a'holder comprising complemental members having eyes at their ends, a series of bends between their ends, and intermediate loops between the bends and projecting oppositely thereto, and coupling means connecting the end eyes of the said complemental members together, the intermediate loops being bent and hooked into one another, and said bends holding the tufts within them under compression.

4. A brush comprising tufts andbinding means for said tufts consisting of two wires having eyes at their ends and bent zigzag. between thelr ends, the outward bends of such wires forming the halves of sockets to receive the tufts, the wires being arranged opposite and complemental to each other embracing the tufts, the intermediate or inward bends thereof forming tongues which are overlapped and bent about one another and hooked together. a

5. A brush comprising tufts and binding means for said tufts consisting of two wires having eyesat their ends andbent zigzag between their ends, the outward bends of such wires forming the halves of sockets toreceive the tufts, the wires being arranged opposite and'complementa'l to each other embracing and applying pressure forcibly against opposite sides of the tufts, the intongues which are overlapped and bent and hooked together, and coupling means pass ing through the end eyes of the complemental wires.

6. Abrush comprising a handle, a series of tufts and means for binding said tufts and connecting them to the handle, said 'terinediate or inward bends thereof forming .75 means comprising complemental members 'each having bends to form the complemen tal parts of sockets and having projecting tongues between said sockets, said members beingarranged to embrace and press upon opposite sides of the tufts and of the han-- dle respectively, and said tonguesbeing-overlapped and interlocked, the complemental members then being held to exert forcible pressure against the tufts and the handle whereby to prevent relative endwise movement of either. Y

7. The method of making a brush which consists in providing a holder'meinber having open-sockets for the receipt of brush tufts and oppositely-projecting open loops,

placing brush tufts in said open sockets, placing a similar and complemental holder menu-- ber upon the opposite sides of the tufts, and

causing the open loop portions of the respective members to overlie one another, and then passing a tool through the openings defined by said overlapping loops and turning the tool so as to bend said loops about one another and to draw the complemental parts of the sockets toward one another against the tufts.

8. The method of making a brush which consists in providing two substantially Slllll- 'lar complemental holder members each having open sockets for the reception of brush tufts and oppositely pro ecting tongues be tween said sockets, placing brush tufts in the open sockets of one of the members,

placing the complementalv member against the tufts, causing the tongues .of the mom bers to overlap, and then forcibly crowdingthe members against the opposite sides of the tufts and securing the overlapping tongues together, thereby binding the tufts frictionally in'the sockets.
